ELASTIC FABRIC.

SPECIFICATION forming part of Letters PatentNo. 758,435, dated April 26, 1904.

Application filed November 2,1901. Serial 1%. 80,888. (No model.)

To all whom it may) concern:

Be it known that I, HENRY J. GAIsMAN, a citizenjof the United States, and a resident of New York city, borough of Manhattan, State of'NewYork, have invented certain-new and.

useful Improvements in Elastic Fabrics, of which the following is a specification.

The object of my inventionis to provide a fabric, such as straps or webs, particularly trousers may be used.

adapted for use in suspenders and other articles of apparel, with such qualities that it will have'a normal curvature produced by the character of the woven elastic strands in the fabric.

In carrying out my invention an elastic fabric, such as a strap or web, has woven within it longitudinally-extending rubber or elastic strands,'a strand or strands on one side of the central or median line having a greater pulling capacity or being arranged to pull with greater force than a strand or strands on the other side of said line, sothat the fabric will normally have a curved form due to the efforts of the strands in seeking to return to their normal conditions after the fabric is removed from the loom.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a face view of a pair of'suspenders embodying my invention. Fig. 2 is an enlarged detail, partly broken, of a piece of fabric, illustrating the method of manufacture; and Fig. 3 is a substantially similar view enlarged.

Similar letters of reference indicate'corra sponding parts in the several views.

. The letter A in the drawings indicates generally a piece of fabric shown in the form of a strap or webbing suitable for use in suspenders and other articles of apparel, and when used in suspenders any well-known or suitable appliances at the ends of the straps for connection with the buttons on the waistbands of In Fig. 1 the fabric A is shown having a normal curvature and the convex edges of the two straps are shown opposed to each other, and they may be connected at their meeting-point by any suitable means such, for instance, as stitching B. Woven within the fabric A are longitudinally-extending elastic strands a, preferably made of rub:

ber and placed substantially parallel and interwoven with the warp and'weft strands a a in any well-known manner. My improvements, however, reside in the arrangement of the elast1c strands m such manner as to produce a normal curvature of the fabric, and

this may be effectedby the different pulling capacity of certain of the strands. v

In Figs. 2 and 3 the elastic strands a are represented as of relatively different size or area in cross-section that' is to. say, a strand or strands on one side of the medianlineof the fabric are indicated as thicker than a strand or strands on the opposite side of said line and the other strands may be of less pulling capacity or sizes. For instance, as shown in Fig. 3, the elastic strand near-the left is relatively thick or'of comparatively large crosselastic strands decrease in size or thickness,

such as by being graduated, or two or more D strands on each side of the median line could be similar. The effect of this relative arrangement of different sizes of elastic strands is that when the completed fabric is in its normal condition the thick strand or strands on one side of the median line will tend to draw the fabric toward that side, and thereby will cause the same to assume a curved form, substantially as indicated in Figs. 1 and 2. When the fabric is stretched while in use, the thicker strands will pull back or resist with greater force than the thinner strands. This will be obvious when it is considered that a relatively thick strand has a greater pulling capacity or can pull with greater force than a thinner strand of'equal quality.

It will be understood that the elastic strands may not only be of greater size on one sideobtained by the inherent pulling qualities of jected to greater tension on one'side of the fabric than on the other during the process of weaving.

My improved fabric may be found useful in various relations, such as in suspenders, garters, armlets, and the like.

It will be obvious that if the elastic strands on opposite sides of the median line of the fabric. have different sizes the other strands may have any desired degree of elasticity or size between these extremes.

Having now described my invention, what I claim'is 1. As a new article of manufacture, a curved flat elastic fabric of greater length than width, having elastic strands extending longitudinally thereof substantially side by side, an elastic strand on one side of the median line of the fabric serving to impart the curve to the fabric, substantially as described.

2. As a new article of manufacture a curved flat elastic fabric of greater length than width having elastic strands extending longitudinally thereof substantially side by side, elastic strands on one side of the median line of the fabric serving to impart the curve to th fabric, substantially as described.

3. As a new article of manufacture, a curved flat elastic fabric of greater lengththan width having elastic strands extending longitudinally substantially on the same plane, elastic strands on one side of the median line of the fabric being under greater tension and thus pulling with greater force than a strand on the opposite side of said line, substantially as described.

4. As a new article of manufacture, an elastic strip having substantially plane faces on opposite sides, and of greater length than width, and provided with elastic strands extending longitudinally of the strip side by side on substantially the same plane transversely of the strip, a strand having a greater crosssection than another, to cause the strip to as sume a curved form between its ends, substantially as described.

5. As a new articleof manufacture, an elastic strip having substantially plane faces on opposite sides, and of greater length than width, and provided with elastic strands extending longitudinally of the strip side by side on substantially the same plane transversely of the strip, a strand on one sideof the median line of the strip having greater crosssection than a strand on the opposite side of said line, the intermediate strands having less cross-section than the first-mentioned strand, substantially as described.
